2014/2013 Flashcards
Ohio State - “Reversal of pulpal and soft tissue anesthesia using phentolamine”
Reduced by about half. Is a vasodilator and allows tissues to clear anesthetic more effectively.
Walton - “Histologic examination of condensing osteitis in cadaver specimens”
CO showed areas of inflammation and no inflammation occupied by CT. bordered by dense lamellar bone replacing normal marrow. All teeth with CO had identifiable etiology that resulted in degenerative pulp disease.
Ohio State - “Buffered lidocaine for I+D”
Sodium bicarbonate buffer did not significantly reduce pain of infiltration or decrease pain of incision and drainage.
McClanahan - “Anatomic investigation of mandibular first molar using micro-CT”
Root end resection of 3mm would remove majority of lateral canals and apical ramifications.
Ohio State - “Effect of pre-op acetaminophen/hydrocodone on efficacy of IANB in pts with SIP”
IANB success in SIP patients 32% in acet/hydro group vs 28% for palcebo group. NSSD. Other spin-off of this study shows no effect on ice testing results after having taken this.
Parirokh, Abbot - “Comparison b/w prescription of regular or on-demand ibuprofen on post op pain after single visit RCT”
Pts were experiencing no spontaneous pain and not moderate/severe pain to be enrolled in this study. No differences noted b/w the two groups at 24 hours or 48 hours after tx.
***Jesperson - “Evaluation of dental pulp sensibility tests in a clinical setting”
Endo ice accuracy = 0.904
sensitivity 0.916, specificity 0.896, positive predictive value 0.862, negative predictive value 0.937
EPT accuracy = 0.75
sensitivty 0.84, specificty 0.74, positive predictive value 0.58, negative predictive value 0.90.
21-50yo more accurate responses. Vital teeth with caries more accurate in testing. Analgesic does not affect sensibility testing.
***Pope - “A comparative investigation of CBCT adn PA radiographs in diagnosis of a healthy apex”
Healthy up to 1mm PDL space enlargement. PDL space 1-2mm or greater on CBCT indicative of pulpal necrosis. (Torabinejad says up to 2mm can be variation of normal)
Ohio State - “Role of ultasonography in differentiating facial swellings of odontogenic origin”
Addition of ultrasonography did not greatly increase number of correct diagnoses. Clinical exam alone was 68% correct dx, clinical exam and ultrasonograpy was 70% correct dx.
Martins - “Clinical efficacy of electronic apex locators”
Apex locators work.
Ohio State - “Anesthetic comparisons of 4% articaine, lidocaine, prilocaine, as primary buccal infiltration of mandibular first molars”
4% articaine SSD better than 4% articaine and 4% prilocaine. Still only had 55% success which is still not high enough.
UNC - “Potential correlation between statins and pulp chamber calcification”
Significant increase in calcification, loss of vertical height fo the pulp chamber with NSSD in M-D width of the pulp chamber in mandibular molars. Possible increase in odontoblastic activity by statins.
